Patent DE-19849676-C1 (DE)
Title: Method for folded connection of metal panels has a bonder applied to the edges prior to folding and with a clinch process to secure the folds before releasing the tool grip
Inventor: ZIMMER ERICH
IPC: B21D39/02
Filed: 1998-10-28
Granted: 2000-02-10
Abstract: A method for joining metal panels, e.g. for automobile assembly, has the edges coated with a bonder and rolled over by a folding jig with folding grips. With the folding tool still gripping the rolled over edge a clinch process is applied at set locations along the fold. This further secures the fold and prevents loosening of the bonder as the folded edges try to spring back. The clinch tool presses through the folding flanges.
